Here is the way to do it

// truly async
@Test
    public void testRetrieveBookAsync() throws Exception {

String address = "http://localhost:"; + PORT +"/bookstore/retrieve";

        WebClient wc = WebClient.create(address);
        Future<Book> future = wc.async().method("RETRIEVE", Book.class);
        Book book = future.get();
        assertEquals("Retrieve", book.getName());
    }




or

// async transport is used to do the sync call
    @Test
    public void testRetrieveBookAsync2() throws Exception {

String address = "http://localhost:"; + PORT +"/bookstore/retrieve";

        WebClient wc = WebClient.create(address);

WebClient.getConfig(wc).getRequestContext().put("use.async.http.conduit", true);
        Book book = wc.invoke("RETRIEVE", null, Book.class);
        assertEquals("Retrieve", book.getName());
    }

and add the dependency:

<dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-transports-http-hc</artifactId>
            <version>2.7.5</version>
        </dependency>

Thanks to Dan for making it so flexible, very nice

Hi

The problem is that HTTPUrlConnection does not support HTTP methods it
is not already statically aware of.

One option will be likely to use the HTTP async transport (which Dan
made to work even in the sync mode) - that one is based on Apache
HTTPClient, another option is to attempt to statically  modify
HTTPURLConnection...


Let me experiment a bit and get back to you.

Thanks, Sergey

Hi All,
I'm facing with the WebClient in order to send a PATCH request to an
OData service.
I tried with the following statement

final Response res = client.invoke("PATCH", obj);

but the following exception has been thrown

Is there someone that can help me to achieve my target?

Thank you in advance.
